ABSTRACT
Ethiopia is home to a remarkable diversity of more than 1000 species of medicinal plants. The Harari and Oromo communities living in the prehistoric town of Harar and the surroundings have long history of knowledge and practices of treating human and livestock ailments using medicinal plants. However, this has remained little or no empirically studied. Semi-structured interviews, discussions and guided field walks were used to collect data from 80 randomly and systematically selected informants among who 16 were traditional herbalists. Relative Frequency of Citation (RFC), Cultural Importance Index (CII), Informant Consensus Factor (ICF), Use Diversity (UD), Non-parametric Kruskal Wallis, and Wilcoxon tests were conducted using R software version 3.3.4. A total of 142 wild and cultivated traditional medicinal plant species belonging to 124 genera and 57 families of which leaves are favoured by traditional healers were identified as herbs. Concoction, or filtering, and infusion, or boiling, were the most practiced methods of remedial preparations of the wild and cultivated medicinal plants, respectively. The highest ICF value was recorded for treating toothache and mouth infections (0.93) followed by gastritis, heartburn/pyrosis (0.84). The most culturally important and the highest diversity index were found to be Ocimum lamiifolium and Allium sativum. There were valuable and diversified wild and cultivated ethno-medicinal plant species associated with indigenous knowledge. The reputability of the indigenous knowledge should be corroborated with phytochemical and pharmacological analyses. Moreover, the status of conservation of these plant species and associated ethnomedicinal knowledge needs further investigations.

INTRODUCTION
Traditional herbal medicines continued as inexpensive and easily accessible source of treatment in the primary health care system among varied communities in Ethiopia [1-6]. Local knowledge of herbal medicines in Ethiopia and their uses provided imperative contribution to human and livestock healthcare needs throughout the country [7-10]. Out of 6028 species of angiosperms reported in the flora of Ethiopia [11], about 1000 species were used in the traditional health care system [1]. About 80% of Ethiopian population relies on traditional medicine to treat different types of human ailments [3, 8, 12] because of high cultural acceptability of healers, presence of local pharmacopeias, and relatively lower cost of traditional herbal medicine [1, 5, 13].
Ethnobotanical knowledge and the traditional medical systems contributed a lot in the discovery of modern drugs, for instance, vinblastin and vincristine made from Catharanthus roseus L (Apocynaceae), anticholesterol from Cynaras colymusL L (Asteraceae), and so forth [14,15]. In addition, the preparation procedures indicated in the traditional system suggested better extraction methods for modern drugs [16]. Hence, documenting and safeguarding traditional medicinal plant species and related indigenous knowledge has became crucial subject in the utilization, planning, and management of natural resources such as medicinal plant species [17-19].
In the Harar town and its vicinities, medicinal plants and their uses are widely practiced, as a part of an ancient and indigenous social epistemology. This adaptive knowledge system of the community has remained integral so far among the elderly people, but it has been little studied [5, 20]. For example, the most recent study conducted in the area indicated that 38 traditional herbal medicines were utilized to treat cancer, tumors and inflammatory illness [21]. However, both the medicinal plants and indigenous knowledge system were seriously deteriorated due to the rapid environmental, cultural, land use and socio-economic changes.

It is believed that the study area harbors useful traditional medicinal
plant species used to treat diverse human ailments. It also retains
ancient and reputable indigenous knowledge, which potentially attracts
interests of phytochemical and pharmacological analysts as well as of
conservationists of valuable traditional medicinal plant species and
associated ethnomedicinal knowledge. Moreover, the declining of
traditional know-how on the identities and uses of herbal medicines
between generations could stimulate an urgent ethnomedicinal studies
for in-depth investigation and documentation before it is lost.
The Harari Region, with the capital of the ancient prehistoric town of
Harar having an age of more than 1000 years [22], was explored for age-
old traditional practices of treating diversified human ailments by the
Harari and Oromo communities. In this ancient and momentous study
site, a typical mountain locally called "Garaa Hakim" (Oromo language)
or "Aw Hakim" (Harari language) is the main source of traditional herbal
medicines [21]. Due to higher diversity of plant species harboured in the
mountains and valley complex of the study area, and the primeval
history and civilization of the local people, it was hypothesized that the
share of medicinal plant species and the value of related indigenous
knowledge are expected to be higher and interesting for researchers.
The intent of this study is to analyse the relationship among the
historical epistemology or traditional practices, the diversity of the
medicinal plants and the level of informant consensus on these in the
specific study area of the prehistoric Harar town, the capital of both of
Eastern Hararghe zone of Oromia and the Harari Region. In addition, this
study aims at examining the trend of traditional knowledge with respect
to the identity and use of herbal medicines [23]. It is believed that
acomprehensive ethnomedicinal investigation such as this study shall
contribute to not only safeguarding the deteriorating ethnomedicinal
knowledge but also for conserving the medicinal plants as well as scaling
up the study to phytochemical and pharmacological analyses which
might lead to the discovery of newer drugs [24, 25].
MATERIALS AND METHODS
Study area
The age-old, historic town of Harar and its surrounding is situated in
eastern part of Ethiopia, 515 km from the capital city, Addis Ababa.
Available resources indicated that, Harar town was founded 1000 years
ago [22]. The dominant in the town and its vicinities are Oromo and Harari
communities. The altitude ranges between 1310 (Erer Valley) to 2250
(Aw-Hakim Mountain) meters above sea level (m.a.s.l.).
Topographic feature of Harar and the surrounding is dominated by
mountainous and undulating landforms, including rugged terrain,
steeply sloping hills and valley bottoms [26]. In this age-old and historic
place, a peculiar mountain locally called Gaara Hakiim (in Afaan Oromo)
or Aw Hakim (in Harari language) is abounds with main source of
medicinal plants [21]. The Hakim Mountain is located at the southern
margin of town forming the highest peak (2250 m.a.s.l.), having a north
to south orientations (see Figure 1).
Figure 1: Map of the study area with sampled Kebeles (the smallest
administrative units).
The average annual daily temperature of the area is 19.3 0C, while the
annual average minimum and average maximum daily temperatures are
13.1 and 25.3 0C, respectively. February to May are the warmest months
whereas November to January are the coldest months. The length of
crop growing period ranges from 94 to 135 days, with recorded
fluctuations of five to ten days in a year. There is high variability of
annual rainfall, ranging between 275 to 1000 mm and the average
annual rainfall being 669 mm. The rainfall pattern of the area is bi-
modal, occurring from February to April (short rainy season) and June to
August (long rainy season) [5, 26].
Sampling and data collection methods
Ethnomedicinal data were collected in two different seasons, that is,
from April to June 2017 and September to October 2018 following the
two rain seasons. Participatory Rural Appraisal (PRA) techniques as
recommended by Martin [27] and Cunningham [28] was employed to
collect the data from six randomly sampled Kebeles (two town and four
rural Kebeles). The Kebeles are Gelmashira and Harar Ketema from town
area and Soofi, Awu-Umar, Erer Haweye and Hasengedoo from the rural
areas (Figure 1).
Purposive sampling technique was used to select eighty informants (52
men and 28 women) belonging to both the Harari and Oromo
communities so that they have been provided their comprehensive
ethnomedicinal knowledge of both wild and cultivated plant species.
Among these, 16 (10 men and 6 women) key informants (traditional
healers) were selected using purposive sampling technique, guided with
the community leaders, elderly people and members of local
community. The rest of the 64 informants (42 men and 22 women) were
selected with stratified random sampling method. Finally, households of
the selected study sites were registered and stratified into three age
groups, youths (20–35, n=26), adults (36–65, n=36) and elders (above
65, n=18) because one of the key objectives of the study was to find out
how the knowledge varies with age.
Semi-structured interview and group discussion was employed to collect
information from the participants. Following the Oromo and Harari
custom, before carrying out the interviews and group discussions,
156
Journal of Ayurvedic and Herbal Medicine|July-September|2020
traditional ceremonies and blessings were conducted. Then, oral Prior
Informed Consents (PIC) was confirmed from each informant.
The semi-structured interviews with the 80 respondents and group
discussions were administered in the local languages, Harari and Afaan
Oromo. For the group discussions, the participants were grouped into
four and the discussions were carried out with average of 8 hours per
group). A detailed information about the local name(s) and descriptions
of the plant species, how and why it is used for treatments, specific types
of ailment treated or controlled, medicinally used parts, conditions and
methods of preparations, remedial administration routes, and basic
drawbacks, were collected. Additionally, field walks guided with key
informants were used to collect medicinal plant species for voucher
specimens supported with documentation of photographic and field
notes. Moreover, interviews with key informants were carried out in the
field in order validate the data and to avoid the likely chance of
confusing identities of plant species by repeated inquiries. These
activities were done twice or-thrice with the same and different
respondents to confirm the validity and reliability of the recorded data.
Specimens were collected and coded in the field, later identified using
volumes of the Flora of Ethiopia and Eritrea for taxonomic keys and
through visual comparisons with authenticated plant specimens kept at
the Herbarium of Haramaya University (HHU). Two copies of voucher
specimens of all the traditional medicinal plant species were kept in
HHU.
DATA ANALYSIS
The total number of medicinal plant species, its growth habit, parts used,
number of remedies prepared, number of illnesses treated using it,
formulation types and routes of administration were all analysed
quantitatively [27, 29]. Particularly, the quantitative analyses focused on
the degree of agreement among the different respondents concerning
the uses of plant species, the benefits, and the importance vis-à-vis to
the diverse human ailments it is used to treat. For this, quantitative
indices, particularly, the Relative Frequency of Citation (RFC), the
Cultural Importance Index (CII), the Informant Consensus Factor (ICF),
and the Diversity of Uses (DU), were employed.
The informant consensus factor (ICF)
The ICF of each medicinal plant, the proportion of informants who
independently reported its use against a disease category, was
calculated using the formula developed by Trotter and Logan [30]:
ICF = (nur–nt)/ (nur–1)
Where, nur refers to the “number of use-reports in each disease
category” and nt refers to "the total number of species used for that
disease category".
The relative frequency of citation (RFC)
The Relative Frequency of Citation (RFC) index, for each medicinal plant
species documented, was calculated based on the Frequency of Citation
(FC) values [31] as follows:
RFC = FC/N.
Where, N is the total number of informants while FC was calculated as:
FC = (Number of times a particular species was mentioned) / (total
number of informants) × 100.
Then, the RFC index was calculated by dividing the FC value of each
species by the total number of informants participating in the survey (N).
The Cultural importance (CI) and use diversity (UD)
The cultural importance (CI) index refers to the sum within species
across all plant-uses of the number of informants reporting a plant-uses
over the number of respondents reporting the plant (Tardio and Pardo-
De-Santayana, 2008), while diversity of uses (DU) designates the
Shannon diversity of uses Index [32].
To evaluate the depth of knowledge with age categories, the
nonparametric Kruskal Wallis Test was performed. If there was a
significant difference between the informant’s gender and knowledge of
use of traditional medicinal plants, the non-parametric Wilcoxon test
was performed pair wise using R software version 3.3.4 for Windows by
using multicompview and r companion packages. P-value of less than
0.05 was taken as statistically significantly different.
RESULTS
Diversity of medicinal plants and their uses
The Table 1 below shows a total of 142 traditional medicinal plant
species obtained in this study, all of which were cultivated plants species
used for diverse medicinal applications by both the Oromo and Harari
communities. These belonged to 124 genera and 57 families. Among
these, 47 plant species belonged to 43 genera and 27 Families. Three
families, namely Asteraceae, Lamiaceae and Myrtaceae, each belonging
to four species, accounted 12 of the cultivated medicinal plant species.
However, four families, namely, Apiaceae, Brassicaceae, Rosaceae and
Rutaceae had three species each. These seven families consisted of 24
(about 50%) of the total cultivated medicinal plant species.
The cultivated medicinal plant species were neutraceutical (edible and
medicinal), among which 48.9% were aromatic and, hence, the most
popularly used as spices or condiments. The rest of the cultivated plant
species were used as fruits (7 species), vegetables (5 species), stimulants
(3 species) and oil (1 species). The most popular non-edible cultivated
medicinal plants used by the communities for different human ailments
are: Aloysia triphylla (L’Herit.) Britton, Artemisia abyssinica Sch. Bip. Ex.
A. Rich., Azadirachta indica A. Juss., Cymbopogon citratus (DC.) Stapf,
Echinops kebericho Mesfin, Hagenia abyssinica (Bruce) J.F. Gmel, Myrtus
communis L., Ocimum basilicum L. var. thyrsiflorum (L.) Benth, Ocimum
lamiifolium Hochst. Ex Benth, Vernonia amygdalina Del, and Withania
somnifera (L.) Duna.
The growth form or the habitats of the cultivated traditional medicinal
plant species are displayed in Figure 2 below. The annual herbs
constituted the highest number of species (18 species accounted
38.3%), followed by trees (16 species accounted 34%) and shrubs (10
species of 21.3%). Climber, grass and perennial herbs were represented
by one species which accounted 2% each.
The growth form or habits of the wild traditional medicinal plant species
is shown in Figure 3. The annual herbs constituted the highest number
157
Journal of Ayurvedic and Herbal Medicine|July-September|2020
of species (49 species accounted 51.6%) followed by shrubs (24 species
accounted 25.3%) and trees (12 species accounted 12.6%).
The wild medicinal plant species which are used for diverse medicinal
applications (Table 2) accounted for 95 plant species grouped into 81
genera and 44 families. Seven families, namely, Asteraceae (13 species),
Fabaceae (10 species), Lamiaceae (10 species), Acanthaceae (4 species),
Crassulaceae (4 species), Euphorbiaceae (4 species) and Rubiaceae (4
species), were accounted for 49 (51.6%) of the wild traditional medicinal
plant species.
Below, Figure 4 shows the reported cultivated medicinal plant species.
According to the obtained data, nine different parts of plants were used
for 111 remedial formulations. Leaves were the most utilized parts of
plants (45.9%) followed by the seeds (25.2%) and fruits (13.5%) in the
formulations (Figure 4).
The obtained data shows 16 different parts of plants were used for 169
remedial formulations. Leaves were the most utilized parts of plants
(45.6%), followed by roots (19.5%) and fruits (8.9%) (Figure 5). This
figure also shows the use of different wild medicinal plant parts in
remedial formulations, the number and percentage of preparations per
plant part.
Methods of preparation and routes of administration
The informants reported 155 remedial formulations, which are
categorized into 25 use-types from the 95 wild medicinal plant species,
while, 100 different remedial formulations, which are categorized into
19 use-types, were reported from the 47 cultivated medicinal plant
species (Table 3).
With regards to the depth of knowledge about the traditional medicinal
plant species, informants in the youth age category ranging 20–35 years
was found relatively lower (p=.002), whereas elderly informants in the
age category above 65 was rich (p =.006). The depth of knowledge for
adult informants within the age category 36–65 was found high (p =
.004). The binomial test (b= 2.08, SD = 34.4, p = 1.06e-02) on the depth
of ethnomedicinal knowledge between the young, the adult, and the
elderly informants showed significant differences (p > .05).
Informant consensus factor (ICF) and frequency of citation
The most common health problematic categories for the population
were identified by traditional healers based on their experience on
frequency of ailments treatment. In this respect, a total of ten ailments
were reported as the most common health problem categories (Figure
4). The FIC value for these most challenging health problems of the area
ranges between 0.93 and 0.70. The FIC is higher for toothache and
mouth infections (0.93) and relatively lower (0.70) for abdominal
disorders, which involves stomach disorder, loss of appetite,
stomachache, blown stomach, flatulence and indigestion, and sudden
diarrhea.
Cultural importance (CI) and use diversity (UD) indexes
The obtained data shows that the medicinal plants like Ocimum
lamiifolium, Allium sativum, Osyris quadripartita, Hagenia abyssinica,
Echinops kebericho and Moringa stenopetala scored relatively higher
value of both cultural importance (CI) and use diversity (UD) indexes
(Table 5).

DISCUSSION
For both cultivated and wild medicinal plant species, the herbaceous
plant specie accounted for higher number and percentage. A number of
research reports indicated herbaceous plant species were more
preferred than woody plants for traditional medicinal purpose due to
comparative ease of collection, and easiness of remedial formulations,
which could have relatively little impact on the natural vegetation,
hence good for conservation of source, especially when the plant is wild
[8, 33, 34]. As was also reported by different authors [21, 35-37], most of
these wild plant species were used to treat similar health problems
which this finding reveals. Moreover, the finding indicates that Hakim-
Gara/Aw-Hakim mountain, harbours high levels of floristic diversity and
ideal site for collection of traditional medicinal plant species [21]. Indeed,
among the 95 wild traditional medicinal plant species, sixty-two of
medicinal plant species (65.3%) were collected from this mountainous
landscape. As was reported by 88% of the informants, the name ‘Hakim-
Gara’ itself literally means ‘the Mountain of Healing’, or ‘the Healing
Mountain’ in Afaan Oromo. It comes from hakim which means
‘physician, healer’, itself from hakkama/akkama ‘to live healthy life’, and
gaara ‘mountain, peak’.
Nevertheless, the largest proportion of younger generation in the study
area was found to be less knowledgeable about the types and values of
the traditional medicinal plant species. This might be attributed to the
current expansion of modern education and health care facilities. It is
believed that this situation made the young generation to focus on
modern medicines at the expense of the traditional wisdom. Similarly,
the decline of indigenous knowledge on medicinal plant species and
associated indigenous knowledge throughout the generations was
reported in some other cultural groups in Ethiopia [2, 3, 38].
The findings of this study have indicated that both internal and external
routes were used for herbal applications. For cultivated medicinal plant
species, 72% were internal application whereas 28% were for external
(topical) application, but, 40% of the wild medicinal plants were
prepared for internal and 60% for external applications. The oral route
of administration accounts the highest percentage for the cultivated
traditional medicinal plants since most of these cultivated plant species
are edible and might have minimum effect on the dose and precision.
Likewise, some previous studies indicated that oral route of
administration was the most common [2, 21, 39, 40]. However, the
percentage of preparation for internal (oral) use is much less than that
of external use for wild traditional medicinal plant species. Nonetheless,
there was no harmony on the prescribed amount used and frequency of
medication among the traditional healers. Most of them reported that
the dose given to patients depended on age, physical and health
conditions. Lack of accuracy and standardization were mentioned as a
global drawback of traditional healthcare system [41].
What’s more, the higher values of FIC for toothache and mouth
infections and gastritis heartburn/pyrosis disease categories indicated
that there was high agreement on the treatment of these major health
problems of the study area. The highest consensus goes for toothache
and mouth infections. This will attract pharmacologists for further
pharmacological exploration of the traditional plant species in this rich
ethnomedicinal knowledge and practices area. It has been reported that
pharmacologically effective antidotes are expected to have greater FIC
value and vice versa [30]. Therefore, the FIC results could be useful in
prioritizing medicinal plant species for further pharmacological studies
since efficacy of traditional medicinal plant is strongly correlated with
FIC value [8, 42].
The Relative Frequency of Citation (RFC) values for both cultivated and
wild medicinal plant species identified in this study ranged from 0.86 to
0.04. The highest RFC, above 0.50, was recorded for Allium sativum,
Ocimum lamiifolium, Linum usitatissimum, Osyris quadripartita,
Hagenia abyssinica, Echinops kebericho, Lepidium sativum, Withania
somnifera, Phytolacca dodecandra, Moringa stenopetala, Rumex
abyssinicus, and Azadirachta indica. The RFC values indicated that, there
was a considerable level of harmony on the therapeutic value of
traditional medicinal plant species used in the study area. The higher
RFC values of ethnomedicinal plants species indicated the profuse
application and widespread knowledge of them among the local
communities [42].
In general, this study indicated that in most parameters of importance
matrix, similar set of traditional medicinal plant species ranked top
except that some disorder in their rank, between measurable indices
was detected. When the ethnospecies have high importance values in
all/most indices, it could explain the importance of those plant species
for the respective applications by the local communities [43].

CONCLUSION
Overall, this comprehensive ethnomedicinal study has shown that the
Oromo and Harari communities of the study area relied on substantial
number of traditional medicinal plant species to treat wide spectrum of
human ailments and are knowledgeable about the characteristics and
applications of medicinal plant species. The majority of medicinal plant
species were harvested for their leaves pose no significant threat to the
natural vegetation of the study area. This study revealed that varieties
of plant species are playing important role for treating different human
diseases. Indeed, the traditional healers have accumulated a stock of
ancient indigenous knowledge on usage of plant medicine, a vital
knowledge and skills inherited through and over generations. Besides,
the therapeutic use of the documented plants will provide basic data for
further research that focus on pharmacological studies and the
conservation of the most important medicinal plants.
The binomial test on the depth of ethnomedicinal knowledge between
younger and elderly informants showed a significant difference. Many
young people have acquired little or none of their fore-parents’
knowledge. This shows the high level of deterioration of ethnomedicinal
knowledge in this ancient historic society. It is, therefore, crucial to
preserve this indigenous knowledge on traditional medicinal plant
species through proper documentation, identification of plant species,
herbal preparation and dosage, and also to train the new generation and
incorporation of such important indigenous knowledge in formal school
curricula. In addition, phytochemical and pharmacological analyses are
advised in order to give scientific ground to the existing ethnomedicinal
knowledge.
